Vehicle's airbags did not deploy upon collision with two concrete walls, causing a life threatening tbi and also severe damage to the left arm which resulted in it's inability to control/use below the elbow, and especially the hand. This was due to the brachial plexus injury that was caused when the airbags did not deploy as they were supposed to. I have attached the report from police and insurance company (with photos).

Takata recall airbag has not been replace

12/21/2018 ODI #11163053.0

Takata air bags. I have been to the GMC dealership service department several times over the last 2-3 years since the recall was placed on my pickup for the takata air bags trying to get the air bags replaced or fixed. I have been told that gm has not come up with a solution or resolution for my vehicle to replace or repair the recalled takata air bags. This absurd that the recall has gone on this long and gm does not have a plan or a way to repair or replace the takata air bags in my 2008 GMC sierra 1500 pickup truck. Please look into this and force them to fix these air bags before more people are killed or severely injured.

Began to smell faint raw gas fumes around the vehicle in the summer. In the autumn months the raw gas odor smell intensified and was very strong with an overcoming presence in the cabin while driving. I brought the vehicle to my shop for diagnostic. The mechanic (non GMC garage) called back several hours later and said I had been driving a potentially disaster. He asked me to see for myself. I was able to view this first hand after he had removed the fuel tank from the vehicle. The fuel pump is mounted into a deep sump on the top of the gas tank. The sump well is rather deep and collects mud, silt, debris and water while driving and that collects and build up over time into the sump and that stays moist at all times.
